Migrate to libyang2

libnetconf2: getSchema and getConfig were no longer used in netconf-cli,
so I deleted them. They can get readded once the bindings get split into
a separate project.

sysrepo_access: Some sr_val stuff was removed.

YangSchema: type descriptions are not available
            availableNodes returns only input nodes for RPC nodes
            impl_getSchemaNode: no longer disables error printing

libyang: No longer supports leafrefs without the leaf it points to.
